Yep I wanted to say that too :D

NixOS, contrary to arch and the other Linux distributions, does not use
ld cache, and consequently do significantly more "stat()" stress on the
file system each time it charges an executable with dynamic libraries.

In case of something like a python software, which load hundred shared
objects for its module resolution, and on machine with low-RAM / low-IO
, that can be very significant.
